Title: Sliding caliper disc brakes
IPC: F16D55/224
Filed: 1973-04-05
Abstract: 1428026 Disc brakes GIRLING Ltd 29 March 1974 [5 April 1973] 16264/73 Heading F2E A disc brake comprises a fixed torque plate member, a caliper member 10 mounted on the torque plate member for moving friction pad assemblies 26, 28 into engagement with a rotatable disc, a first releasable connection (e.g. 40, 42, 44) between the caliper member 10 and the torque plate member permitting sliding movement of the caliper member 10 relative to the torque plate member, and means (e.g. 52, 54) on said members independent of the first connection to provide a second connection between the caliper member 10 and the torque plate member permitting pivoting of the caliper member 10 relative to the torque plate member when the first connection is released thereby to gain access to the pad assemblies 26, 28. In the embodiment illustrated the first connection comprises two pin assemblies 38 each of which comprises a plunger 40 slidable in an oversize bore 42 in the torque plate member and a clamping screw 44 by which plunger 40 is clamped to a lug 46 extending from the caliper member 10. The plunger 40 is formed with grooves housing resilient bearing elements which centre the plunger in the oversize bore 42. Alternatively the pin assemblies are secured to the torque plate member and slidable in respective openings in the caliper member. The means providing the second connection comprise aligned bores 52, 54 formed in lugs 50, 56 provided on the caliper member 10 and the torque plate member respectively. The bores 52, 54 are dimensioned to temporarily receive a pin 20 which normally retains the pad assemblies 26, 28. Thus to gain access to the pad assemblies 26, 28 the pin 20 is withdrawn from bores 22 in limbs 14, 16 of the caliper member 10 and introduced into one or other of the sets of bores 52, 54. Both clamping screws 44 are removed and the caliper member 10 is pivoted about pin 20. The bores 52, 54 may be out of alignment in the normal operative position of the members in which case at least one of the pin assemblies 38 must be dismantled before the retaining pin 20 is transferred to the bores 52, 54. The pivotal connection between the members may be provided between interengageable formations on the members for example a spigot on one member engageable in an opening in the other member. As shown, the limb 16 of caliper member 10 is formed with a pair of hydraulic cylinders 34 each containing a piston 36-an independent hydraulic supply may be provided for each of the cylinders 34 and the cylinder bore sizes may be unequal. The pistons 36 apply pad assembly 28 to the disc and pad assembly 26 is applied by sliding movement of the caliper member 10 with respect to the torque plate member. In addition to being retained by the pin 20, the pad assemblies 26, 28 are guided by pairs of lugs 30, 32 extending inwardly from arms 12 of the torque plate member.

Title: Improved means for controlling the tension of coils or rolls of flexible material
IPC: G01L5/06
Filed: 1929-05-28
Abstract: 332,991. Callender's Cable & Construction Co., Ltd., Richardson, A. B. F. G., and Spencer, J. A. May 28, 1929. Feeding webs.-In an arrangement for frictionally controlling the tension of flexible material, such as a strip of paper or a length of fabric, which is being drawn from a coil or roll, the friction is produced by a spring, the tension of which is varied by the movement of a nut along a screwthread, the nut boing rotated by gearing from the coil-holder, so that the frictional restraint is reduced as the radius of the coil diminishes. In the form shown in Fig. 1, two coils 9, supported on a spindle 1, are pressed against a friction disc 5 mounted on the spindle. Each coil is mounted on a rotatable hub 10, which can slide on the spindle 1 and carries a disc 11, the coil being gripped between the disc 11 and a disc 14, which is loosely mounted on the spindle and bears against the friction disc 5. A spring 15 is interposed between the hub 10 and a rotatable member 17, which is connected to the hub by a clawcoupling. The member 17 frictionally engages a non-rotatable member 20, which can slide on the spindle and abuts against a nut 21, which engages a screw-thread on the spindle. The nut 21 is slowly rotated, as the size of the coil diminishes, by a worm-wheel 29 driven by a worm 28, which is connected by gearing with a worm 26 on the periphery of the member 17. In a modification, the two coil-holders bear against ball thrust-bearings located between them on the spindle, and a travelling nut 21 is provided in connection with one coil only, but serves to control the braking force on the other coil. The movement of the nut is transmitted to a sliding collar, which forms an abutment for the spring of the other coil-holder, by means of screw-andnut mechanism and a rod passing through the spindle. In another form, the hub of the coilholder carries an eccentric, which operates ratchet-mechanism by which the nut 21 is rotated.

Filed: 1939-06-05
Abstract: 530,168. Refractories. DOUGLAS, M., BRADLEY, A. L., and CHESTERS, J. H. June 5, 1939, No. 16485. [Class 22] Moulded dolomite-magnesite refractories, particularly bricks are made by grinding a stabilized dolomite clinker separating from the ground clinker fractions of coarse and fine grain size, mixing together proportions of such coarse and fine fractions with a proportion of dead burned magnesite (including sintered and electrically fused magnesia) of grain size intermediate between those of the coarse and fine fractions of the dolomite. In an example ground dolomite is mixed with a stabilizing medium such as magnesium silicate or silica and borates or phosphorus may be added to prevent the beta to gamma inversion of any di-calcium silicate formed. It is then sintered, ground and graded to give a coarse fraction passing through a 3/16 inch sieve but retained by a 12 B.S.S. sieve and a fine fraction passing through a 100 B.S.S. sieve. The coarse fraction (55 parts) is mixed with the fine fraction (25 parts) and with dead burned magnesite (20 parts) having an intermediate grain size.

Title: Preparation of plastic-metal products including laminates composite  tubes and the like
IPC: B32B15/08
Filed: 1971-05-24
Abstract: 1356803 Metal-plastics laminates R W ERWIN 24 May 1971 [28 May 1970] 16633/71 Heading B5N [Also in Division F2]  Fluorinated or perfluorinated hydrocarbon polymer plastics film is adhered to a metal surface without use of adhesive by applying heat to soften the plastics and bond it to the metal, heating and bonding taking place under reduced pressure, to prevent entrapment of air, and without application of pressure to the external surface of the film. The plastics is preferably a tetrafluoroethylene polymer (e.g. hexafluoropropylene-tetrafluoroethylene copolymer) and may be applied to each face or to one face only of a metal sheet; the exposed faces of the plastics may have been chemically treated for adhesion to other materials. The metal may be Al, Fe, Cu or an alloy thereof (e.g. Cu-Ni, brass containing Al) and may be oxidizable or non-oxidizable at the bonding temperature, e.g. 450-625‹ F.; its surface may be flat or curved. Laminates prepared by this method are used to make tubes for use as pipe-liners (see Divisions B8, F2). An exposed metal surface may have an edge strip of the plastics bonded thereto to facilitate tube manufacture. As shown in Fig. 9, a metal sheet 13 and a plastics sheet 14 are disposed upon a longitudinally-extending stiff metal coil 11, which is supported in a slot 16 in a pipe 7 and whose turns are spaced apart by end strips 12 to allow room for the initial expansion of the plastics sheet which takes place on heating. The assembly is held by straps 10 and is supported inside a cylinder which can be closed, evacuated and subjected to heat. As shown in Fig. 11, the laminating operation is carried out in a closed metal apparatus comprising containers 18, 19, 20 and curved conduits 22, 25, which can be evacuated at 21 to produce'a substantially complete vacuum. Two plastics films 28a, 29a are bonded to one face of a metal sheet 30a (which has previously been cleaned by solvent) by applying heat at 23. The assembly is (optionally) partially cooled in zone 24 and the plastics-coated face is coated with a release agent, e.g. silicone, by a roller 34 to prevent sticking to the conduit 25. Two plastics films 37a, 38a are then similarly applied to the exposed metal face of the assembly.

Abstract: 561,681. Fluid-pressure servomotor control systems ; valves. ARMANDIAS, L. S., and ASSOCIATED MESSIER INVESTMENTS, Ltd. Nov. 25; 1942, No. 16748. [Class 135] A control valve device for controlling the clutch in the drive of a hydraulic pump comprises a pair of lift valve members actuated by oppositely extending piston rods on a piston subject to the controlling pressure. In the hydraulic circuit shown in Fig. 1, a pump 1 draws liquid from a reservoir 4 and delivers it to a pressure-loaded accumulator 7 with a service outlet 11. The pump 1 is driven through a clutch held in engagement by a spring device 3 and released by admitting pressure fluid to a power device 2 under the control of a valve device 18. This device comprises a cylinder 36 closed at each end by covers 43, 44, held in place by screwed plugs 39, 40 and housing a piston 41 provided with piston rods 50, 51 passing through stuffing boxes 48, 49 in the covers into valve chambers in the plugs. One side of the piston is subject to the pressure in the accumulator 7, while the other side is subject to the pressure in an auxiliary loading accumulator 22. Each valve chamber has an inlet and outlet connection and houses a spring-loaded lift valve formed on the end of a ported tubular member. When the pressure in the accumulator 7 rises above that in the loading accumulator 22, the piston moves to left to open valve 56 to connect pipes 16 and 33 and admit pressure to the clutch releasing power device. In a modified arrangement, the clutch is released by spring and is moved into engagement by fluid pressure.
